    Did you try 2hz/1hz for the high/low fails as well as setting the counts to a lower number and setting the two "time" related ones to zero.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    My E40 will not properly fail the MAF unless fail hi/low are at 0/0. With the commonly recommended 2/1 it would show MAF status as 'Fail' and set the codes but would not run at all with the MAF tables zeroed out. 0/0 made it start acting right. No I don't know why.
